摘　　要：利用金属切削仿真软件Advant Edge对AL6061-T6和STEEL1018两种材料的微细铣削开展有限元仿真模拟,揭示微细铣削中的切削力、切削温度等变化规律,利用切屑的形成过程和切削分力Fx、Fy的不同变化规律,分析了最小切削厚度值。通过两种材料切削比能的变化,分析了微细铣削中存在的切削尺度效应现象。开展了微细铣削槽加工实验,分析了槽铣的加工表面形貌和切削力,为微细铣削工艺参数的优化提供依据。In order to studying the principle of cutting force and temperature in micro milling, FEA simulation has implemented to AL6061-T6 and STEEL1018 by AdvantEdge. The minimum chip thickness is preliminary estimated by the analysis of the process of chip formation and different situation of cutting force component, and the size effect in micro machining is also revealed by studying the specific cutting force of two material. The experiment of micro slotting is implemented, the cutting force is measured and the topography of machining surface is analyzed,which give the efficient basis to the optimization of micro machining parameter.
